<div dir="ltr">The purpose of MDAL is slightly different from 3D meshes such as PLY. In 3D mesh, you store just elevation (either face or corners) and some type of materials. But in MDAL, the aim is to store quantities on top of the mesh (e.g. a mesh for ground elevation and water depth on top over a period of time). So in essence, it is more like 2.5D (+time). <div><br></div><div>Cheers</div><div>Saber</div></div><br><div class="gmail_quote"><div dir="ltr">On Tue, 2 Oct 2018 at 13:40, Carlos Henrique Grohmann de Carvalho <<a href="mailto:carlos.grohmann@gmail.com">carlos.grohmann@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">That seems very interesting!
